Emphasis: More conceptual questions

A second full-length 80-question simulation with all-new questions across every WRE topic area. It places a greater emphasis on conceptual, judgment-based questions — like those on the real CBT exam — making it ideal once you've completed Exam 1.

Reference Materials & Exam-Day Policies

Both practice exams use the same NCEES-style simulator interface and the same in-exam reference materials you will have on exam day. Here is what is included and how to prepare.

Reference Materials

The PEwise exam simulator includes WRE-specific reference documents within the exam interface — except for the PE Civil Reference Handbook itself. Due to licensing restrictions, we cannot distribute the NCEES handbook directly.

You can upload your own copy of the PE Civil Reference Handbook into the exam interface to use during the practice exam. To obtain your copy, register or log in to MyNCEES where you can access and download the handbook for free.

Calculator Policy

For calculations, you have two options:

  • Use your own approved calculator — The NCEES-approved calculators for 2026 include:
    • Casio: All fx-115 and fx-991 models
    • Hewlett Packard: HP 33s and HP 35s models only
    • Texas Instruments: All TI-30X and TI-36X models
  • Use the built-in calculator available in the exam interface

Exam Format

This is a timed 8-hour practice exam with 80 questions. It closely mirrors the PE Civil WRE exam format.

PE WRE Practice Exam FAQ

It is a full-length 80-question exam with an 8-hour timer, matching the length and pacing of the real PE Civil Water Resources & Environmental computer-based test. It is timed on purpose, so you build the endurance the actual eight-hour exam day demands.
It covers the full NCEES PE Civil Water Resources & Environmental blueprint on both the water-resources and environmental sides: open channel and pipe flow, pump systems and hydraulics, culvert hydraulics, hydrology (storm probability, runoff, hydrographs, groundwater), water-quality modeling, drinking-water treatment, and wastewater collection and treatment (activated sludge, nutrient removal, disinfection). It is a single 80-question full-length simulation rather than a separate shorter exam.
Yes. Your answers and progress are saved automatically in your browser as you work, so you can close the tab and pick the exam back up later on the same device. The simulator also includes the same scheduled break system as the real CBT exam, which locks the questions you've already viewed once you step away — exactly as it works at the testing center.
Each exam has a built-in TI-36X Pro calculator you can open right inside the exam interface, so you don't need a physical calculator to practice. If you prefer your own, any NCEES-approved model works — the approved 2026 list includes the Casio fx-115 and fx-991 series, the HP 33s and 35s, and the TI-30X and TI-36X series. Practicing with the on-screen calculator gets you comfortable with the exact tool layout before exam day.
The simulator includes the WRE-specific reference documents inside the exam interface, except the PE Civil Reference Handbook itself — NCEES licensing prevents us from distributing it directly. You can upload your own copy of the handbook into the simulator; it is available free once you register or log in at MyNCEES (account.ncees.org). Practicing with the references open trains you to look values up quickly under time pressure, which is half the skill on the real exam.
Yes. The practice exam is built around the current NCEES PE Civil Water Resources & Environmental specifications (last revised April 2024; the next revision is scheduled for April 2027) and the computer-based-test format. Questions are written in NCEES style across the WRE topic areas, and the simulator mirrors how questions are presented, timed, and navigated at Pearson VUE testing centers.
Single-answer multiple-choice questions are scored the standard way: select the one correct option. 'Select All That Apply' questions are scored all-or-nothing — you must select every correct option and no incorrect ones to earn credit, with no partial credit, the same approach the real exam uses. After you submit, every question shows the correct answer alongside a detailed step-by-step solution, so you can see exactly where points were won or lost.
Yes — you can retake the practice exam as many times as you like while your enrollment is active. The question order is reshuffled on every new attempt, so each sitting stays fresh rather than testing recall of a fixed sequence. Your past attempts are saved to your exam history, so you can track how your scores trend as you study.
